But despite the recent advances in our knowledge of the molecular details of furrow specification, there have been few investigations into cytokinesis in parthenogenetically activated embryos that use aster-based spindle assembly and cleavage plane
6c, d), the site of their plus end interaction coinciding with and defining the division cleavage planes
and boundaries of domains.
I have discovered two mechanisms that prevent aneuploidy: the tether-based acentric segregation and the elongation of the cell that clears chromatids from the cleavage plane
Conclusions: The location of the intermuscular cleavage plane
was related to disc level and not correlated with age, height or weight.
There was no cleavage plane
around the vessels and only superior part (in surgical plane) of right M1 and A1 was visible.
The second break occurred along a cleavage plane
within the crystal that fractured during lifting of the specimen.
Though the spindle and its two poles together can determine this cleavage plane
, several researchers have suggested that chromosomes actually mark the location.
This unique instrument gently separates a thin layer of living cells, called the epithelium, on the outside of the eye, along a natural cleavage plane
The renal upper pole was then excised along the atrophic cleavage plane
using a ligasure device.
rosaceus has shifted relative to echinoids with more typical planktotrophic plutei and extends to or above the third cleavage plane
at the equator of the embryo.
The incision was extended and cleavage plane
between the pericardium and epicardium was established.
A cleavage plane
was then formed, and the lesion was excised en bloc with endoscopic instruments.
